To all whom, it may concern Be it moan that l", UBCARJ. Jonfison, a subject of the King of Sweden, residing at-iloquet, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Button Fasteners, of which thejollowing a specification, I

The present invention relates to improvements in buttons and of thattype sometimes termed self-stlaching.

The object in View is to provide a huiton embodying a head or shell adapled to re ceiire an attaching shank, locking means hedisposed on the head for engaging the 'shank'auiomaticaily as the latter is intro iluced thereinto and operable-i0 disenoage said shank by the manipulation of a loc 13g member projecting from saidsheil.

'It is further contemplated to employ a special formoi spring for normally hol ing the locking memher in looking position, said.

spring also forming a closure for die openmg provided in the button head through which the locking member projects.

lngs, similar parts are referred to by like reference characters.

Specifically describing the button of the character hercinhefore mentioned as constructed in accordance with my invention, the numeral ldesignatcs the head which comprises a shell consisting of the body portion 2 and the cap member 3. Aclapad to.

be received inio the head or shell 1 is an attaching shank 4 whereby the button may be properly secured to a garment with due ailowance for the i1lClLBQSS of thema'aerial.

ltwill-"beunderstood in the application for the foregoing styleof button that it may be use for-various purposes where a selfatuffhing article of this nature is desired and slight changes In its construction mayhe Speoificntion of Leticia Eafieas.

The body portion of the shell designaied by the numeral 2 is provided centrally of the some with an opening 5 through which the shank 4a is introduced in securing the button in position. llithin the shcil 1 is disposed scope of il elocking means for engaging the shank;

which means consist of a locking her 6 and a spring member 7. The bar 6, as shown most clearly in Fig. 1 ofihe drawing, is secured at one end h clamping a flange 8 of the body 2 o rer said end in a manner that will permit free lateral movement of the opposite'end of the locking i031. The spring Tis disposed adjacent ihe bar 6 and is formed with a straight contact portion 9 normally hearing against the bar 6 while said spring has also a curved portion 10 following the contour of the body portion 2 of the shell and said body portion is formed with s flange 11 which bent overihe curved portion 10 to prevent displacement of the spring and insure proper cooperation of the same with ihedocking bar 6. The curved portion 10 of the spring T moreover, terminates in a resistance arm ii the extremiiy of which bears against the straight portion 9 of the spring and positively holds the latler agaiusi the locking bar 6. As shown in Figs." 3 and 5 most clearly. the cap ihe "spirit of member of the shell bent about the body portion 2 so as to efl: tively inclose the locking means. a slot 1 5. however being provided in the shell and'through iliis slot the free euremitj of the locking bar projects a suitable distance for manipulaiion of the same? This slot 13 is normally covered by means. of the angularly bent end portion ll of the spring T so that it will be obvious that when the locking bar 6 in ils i ual loci;- ing po ition thc bent portion 1% disposed over said opening, thereby preventing foreign matter from collecting within the shell as well as eliminating likelihood of the clothing catching in the slot accidentally.

At a point intermediate {he length of the bar 6 and juxtaposed with relation to the fipening 5 in iihe' body of the shell said loci;-

ing her is provided with a pair of spaced projeciions or lugs 5 shank i consists preferably of a pointed or 'iaperhig head 4V.

and a base plate 4:". "li hen it is desired in the use of the button hereinhefore desomlsiefl, to. attach the samg gg position. the fl, is

inserted through the material and into the member the projecting extremity of the bar (3 is moved laterally permitting the head 4 of the shank 4 to be withdrawn from the shell.

It will be obvious that the special locking means of my button insures a positive engagement of the detachable shank and that the spring when formed into the shape described presents a very strong tension member for the locking bar.

Having thus described the invention, What I claim as new is 1. In a button, the combination of a head comprising a shell, an attaching shank adapted to be received in said head; a look ing bar disposed in said shell adapted to engage with the shank, means for securing said locking bar, the shell having an opening therein through which the locking bar pro jects, and means for normally holding said locking bar in looking position, said means cooperating With the shell to also form a closure for the opening aforesaid.

2. In a button, the combination of a shell comprising a body portion, a shank adapted to be received in said body portion, a looking bar disposed in said shell adapted to en gage with the shank, a spring adapted to co BEST AVAILAB III COPY operate with said locking bar to normally hold the latter in looking position, flanges on the bodyyportionnith I ll ijprsecuring the p g aiid'rifb iifslie l e ef y p tion, the shell aforesald' fhaving' a slot through whicl the locking bar projects to permit lateral In vei'ment of the locking bar, and the spring aforesaid having one end bent laterally to form a closure for said slot. 3, In a button, the eombination o g (1 comprising a body portion, a shall? ed to be received aid shell,- a locking member secured Within the shell, spaced projections carried bv saidrloeking imeinh'in with Wl'llCh -th sh k isadaptedohi en age, a
